In this paper, a new structure for cooperative learning automata called extended learning automata (eDLA) is introduced. Based on the new structure, an iterative randomized heuristic algorithm using sampling is proposed for finding an optimal subgraph in a stochastic edge-weighted graph. Stochastic graphs are graphs in which the weights of edges have an unknown probability distribution. The pro...

Granulosa cell tumors (GCTs) are tumors that arise from granulosa cells, occurring in women 50 to 55 years of age but may occur at any age whereas Juvenile granulosa cell tumors usually occur in children and adolescents. A three years old girl with breast development but without any significant past medical history was referred to the Pediatric Clinic in Children hospital(University of Medical ...

Data envelopment analysis (DEA) is amathematical programmingapproach for evaluating the relative efficiency of decision making units (DMUs) in organizations. The conventionalDEAmethods require accuratemeasurement of both the inputs and outputs. However, the observed values of the input and output data in real-world problems are often imprecise or vague. Fuzzy set theory is widely used to quanti...

E. Azadegan , R. Ezzati Department of Mathematics, Islamic Azad University-Karaj Branch, Karaj, Iran |||||||||||||||||||||||||||||||Abstract In this paper, we present a new two-parameters family of iterative methods for solving non-linear equations and prove that the order of convergence of these methods is at least four. Per iteration of these new methods require two evaluations of the functio...

t has been shown that stress can induce hyperglycemia in several animal models of type II diabetes (1). Cori theorized a link between the physiologic stress response and development of hyperglycemia. In his experiments with rabbits, Cori demonstrated that continuous infusion of epinephrine exacerbated hyperglycemia (2). Van Loon continued these researches by infusing beta endorphins intracister...
